PCI: imx6: Skip controller_id generation logic for i.MX7D
[ Upstream commit f068ffdd034c93f0c768acdc87d4d2d7023c1379 ]
The i.MX7D only has one PCIe controller, so controller_id should always be
0. The previous code is incorrect although yielding the correct result.
Fix by removing "IMX7D" from the switch case branch.
Fixes: 2d8ed461dbc9 ("PCI: imx6: Add support for i.MX8MQ")
